Air pollution is reducing the life expectancy of the residents of Dhaka, one the most polluted cities in the world, by 7.7 years, says a new study.
The residents of Dhaka could live 7.7 years longer while the average life expectancy in Bangladesh would have been 5.6 years higher if pollution concentrations could have been complied with the World Health Organization (WHO) guideline, said an analysis of data from the Air Quality Life Index, conducted by the Energy Policy Institute at the University of Chicago (EPIC).
The study finds that particulate pollution cuts global life expectancy by nearly 2.2 years.
Bangladesh, known as one of the most densely-populated countries in the world, has been struggling with air pollution for a long time.
In many cases, Dhaka, the capital of Bangladesh, is often found to be the most polluted city in the world in global indices.
Particulate matter pollution continues to rise in Bangladesh. Since 1998, the average annual particulate pollution has increased by 15.3 percent, cutting 0.9 years off the lives of the average Bangladesh residents over the years, it said.
In each of the 64 districts, the levels of particulate matter were found to be at least three times higher than the WHO guidelines.
The most polluted areas of the country are Rajshahi and Khulna divisions as the average residents are exposed to pollution that is more than seven times of the WHO guidelines, reducing life expectancy by more than six years, it added.
